  • I love the Sienna location in Texas. I love the energy of the trainers and I love the variety of the work outs. Each workout has been different and I go between 2-3 times a week. I have only been going for four weeks but I feel so much more energy than I did prior to joining this facility. It is also a plus that there are no schedules or work out times and I can start as soon as I arrive! That truly pushed me to say YES and I have no regrets!
